Technical Abstract: 'Morton' spring oat (Avena sativa L.) was developed at the North Dakota Agricultural Experimentation in cooperation with USDA-ARS and released by the Agricultural Experiment Station - North Dakota State University. HiFi was developed from a series of crosses with the pedigree RPB120-73/RL3038//'Noble'/3/'
Otter'/'Diana//RL3038/'Dal'/4/'Riel'/5/IA B605X with the final cross made in 1991. Morton has been evaluated for grain yield in North Dakota since 1995. Based on 36 location/years, Morton is high yielding and flowers 2.5 days later than the oat cultivar 'Jerry'. It has low hull content and high experimental mill yield. Morton also has excellent crown rust and stem rust resistance. Morton was released to provide a crown and stem rust cultivar with high grain yield potential and stable test weight and is adapted to North Dakota and adjacent regions of South Dakota and Minnesota.
